在类头文件中声明boost asio套接字，接受器和终结点 [英] Declaring a boost asio socket, acceptor and endpoint in a class headerfile

问题描述

我有一个用boost asio制成的TCP/IP服务器，它包装在一个类中.现在，我想在类头文件中声明套接字，eindpoint和acceptor，以便我可以使用该套接字的成员函数.服务器现在在类构造函数中运行.我尝试使用如下初始化列表:

I have a TCP/IP server made with boost asio that is wrapped in a class. Now i want declare the socket, eindpoint and acceptor in the class headerfile so that i can make memberfunctions that use the socket. The server runs now in the class constructor. I tried to use a initialiser list like below:

CommunicationModuleTCPIP::CommunicationModuleTCPIP(bool Server,
                                               string IPAdress,
                                               int PortNumber)
 : Sock(new boost::asio::ip::tcp::socket(IOService));
{
// Constructor code

但这会导致编译器错误.像这样在标头中声明袜子:

But this gives compiler errors. Sock is declared in the header like this:

SmartSocket Sock;

SmartSocket是通过以下方式定义的共享指针.

And SmartSocket is a shared pointer that is defined the following way.

typedef boost::shared_ptr<boost::asio::ip::tcp::socket> SmartSocket;

有人可以告诉我是否可以在头文件中声明套接字，接受器和终结点并初始化这些对象吗?

Can anybody tell me is it is possible to declare a socket, acceptor and endpoint in the headerfile and intialize these objects?

欢迎提出任何建议！

下面是te类头文件代码和构造函数代码:

Below is te class headerfile code and the constructor code:

带有端点，套接字和接受者声明的头文件:

Header file with Endpoint, socket and acceptor declarations:

public:

// Constructor and destructor
CommunicationModuleTCPIP(bool   Server,
                         string IPAdress,
                         int PortNumber);
~CommunicationModuleTCPIP();

int Connect();
int Disconnect();
int SendData(SmartSocket sock);
int RecieveData(SmartSocket sock);
int Send(SmartSocket Sock);
int Recieve(SmartSocket sock);
int CheckConnection();

char SendBuffer[20];
char RecvBuffer[20];

SmartSocket Sock;
tcp::endpoint Endpoint;
boost::asio::ip::tcp::acceptor Acceptor;

构造函数，当我在构造函数中创建它们时，注释中的是套接字，端点和接受器.这可行，但我想使这些对象成为类的一部分，以便可以在代码的其他部分的成员函数中使用它们(如果可能的话).

Constructor, in comments are the socket, endpoint and acceptor when i create them in the constructor. This works but i want to make these objects part of the class so that i can use them in member functions in other part of the code (if this is possible?).

CommunicationModuleTCPIP::CommunicationModuleTCPIP(bool Server,
                                               string IPAdress,
                                               int PortNumber){
:Endpoint(ip::address::from_string(IPAdress),PortNumber),
 Acceptor(IOService, Endpoint),
 Sock(new boost::asio::ip::tcp::socket(IOService)

if(Server){

    cout << "Setting up server" << endl;

    //ip::tcp::endpoint Endpoint(ip::address::from_string(IPAdress),PortNumber);

    // Create acceptor
    //boost::asio::ip::tcp::acceptor Acceptor(IOService, Endpoint);

    // Create socket
    //SmartSocket Sock(new boost::asio::ip::tcp::socket(IOService));

    cout << "Before accept..." << endl;

     // Waiting for client
     Acceptor.accept(*Sock);

    cout << "Server set up" << endl;

 }

我得到的编译器错误如下:

The compiller errors that i get are as followed:

推荐答案

唯一明显的错误是初始化列表末尾的流氓;.

The only obvious error is the rogue ; at the end of the initialiser list.

如果删除时仍然有错误，也许您可​​以张贴一个完整的小代码示例来演示错误以及错误本身.否则，很难猜测其余代码可能在做什么.

If you still have errors when you remove that, perhaps you could post a small, complete code example that demonstrates the error, and the errors themselves. Otherwise, it's rather difficult to guess what the rest of your code might be doing.
